U.S. Route 41, also
U.S. Highway 41 (
US 41), is a major north–south United States Numbered Highway that runs from Miami, Florida, to the Upper Peninsula of Michigan. Until 1949, the part in southern Florida, from Naples to Miami, was
US 94. The highway's southern terminus is in the Brickell neighborhood of Downtown Miami at an intersection with Brickell Avenue (US 1), and its northern terminus is east of Copper Harbor, Michigan, at a modest cul-de-sac near Fort Wilkins Historic State Park at the tip of the Keweenaw Peninsula. US 41 closely parallels Interstate 75 (I-75) from Naples, Florida, all the way through Georgia to Chattanooga, Tennessee.
